ts-jest 26.1.2 - "cannot find source file"

[pburkindine]

🐛 Bug Report

When attempting to run jest tests with VSCode debugger in 25.3.1, I keep getting error "cannot find source file" after making seemingly innocuous changes to the spec or tested file. Reverting the changes to the source file allows the tests to run. Reverting to 25.2.1 fixes the error.

System:
    OS: OSX 10.15.4

Npm packages:
    jest: 25.2.7
    ts-jest: 25.3.1
    typescript: 3.8.3

Would you please provide us the reproduce repo ? The information is very limited so it's very difficult for us to investigate. We need:

• a repo
• any useful loggings
• steps to reproduce

Also please follow the bug report template. Those are the useful information that can help us.

Working on a repro

@ahnpnl https://github.com/pburkindine/tsjest-cannot-find-source-file

Just adding foo = 'bar'; to this file produced the error: https://github.com/pburkindine/tsjest-cannot-find-source-file/blob/master/apps/tsjest-cannot-find-source-file/src/app/app.component.ts

(this is the test file: https://github.com/pburkindine/tsjest-cannot-find-source-file/blob/master/apps/tsjest-cannot-find-source-file/src/app/app.component.spec.ts)

After running it the first time and getting the error, I noticed I needed to upgrade jest in the repro to match my environment. After the upgrade, the test passed. Then I changed "foo = 'bar'" to "baz = 'quu'" in the component and ran the test, and it failed again with the log below:

does clear jest cache and rerun help ?

[pburkindine]

yes, running jest --clearCache allows the test to pass, but then changing the value again (e.g. to qum = 'quo') causes it to immediately fail again

[ahnpnl]

oh I think I know, it's related to the fix for #1390 . For some reasons it doesn't work for your case

[rav2040]

I have the same issue with all my typescript projects since the update to 25.3.1. After a successful test run, as soon as I change anything in a source file and run the test again, I get the same error. Reverting the change allows the test to complete.

At the moment, all I can do is keep running jest --clearCache every time I change something, or roll back to a previous version of ts-jest.

I set up an example repo that mimics my project setup if it's of any use:
https://github.com/rav2040/ts-jest-error-could-not-find-source-file

I included a GitHub CI test workflow in the repo. If you look at the workflow logs you'll see the test managed to complete even after I changed the value of 'foo' in the source file.

However, when I do the same thing on my own machine I get the following:

 FAIL  __tests__/index.test.ts
  ● Test suite failed to run

    Could not find source file: '/mnt/f/dev/projects/ts-jest-error-could-not-find-source-file/__tests__/index.test.ts'.

I also tried cloning the repo to a Digital Ocean droplet and running it there, and I still got the same error.

thank you guys for the information, will look into it asap. Stay tune :)

Updated: would you guys please test the fix with this tgz file https://drive.google.com/open?id=1QRnkDOIy7BXQdSjcybzveBkmE1uCU8h5
